Introduction: Known as a potent anabolic drug, teriparatide has a stimulating effect on bone formation, increasing bone mineral density (BMD) and reducing fracture risk.Methods: 11 Caucasian women (mean age 66 years old) with severe osteoporosis treated with recombinant human parathyroid hormone (1–34) – teriparatide (Forsteo) 20 micrograms daily for 24 months were added to the study.BMD at lumbar spine, total hip and f...

Background: The importance of carcinoembryonic antigen (CEA) assessment in the evaluation of medullary thyroid carcinoma is well known. The role of CEA in the assessment of other neuroendocrine tumors (NET) is not clear. We aimed to evaluate a possible correlation between CEA measurements and the aggressivity of NETs.Methods: We evaluated 56 (36 women) NETs followed in a tertiary center (23 gastrointestinal, 12 pancreatic, 10 pulmonary, 7 without primary...

Introduction: Medullary thyroid carcinoma (MTC) is an aggressive neuroendocrine tumor derived from C cells that is responsible for approximately 5% of the gland malignancies, most of them occuring sporadically. Lymph node metastasis may occur early in disease pathogenesis and is one of the most important negative prognostic factor. Surgery is the only curative therapy while other chemotherapeutic options are limited. Neuroendocrine differentiated C cells may express somatostat...

Introduction: There is evidence that SARS-COV-2 infection can result in development of endocrine disturbances. Expression of the angiotensin-converting enzyme 2, which is postulated to be at the center of the pathogenesis of COVID-19, has been reported in various endocrine tissues.Case Series: We retrospectively analyzed 12 patients with recent history of SARS-COV-2 infection: 5 cases with subacute thyroiditis (SAT), 2 cases with Graves’ disease, 2 ...

Introduction: Pituitary tumours may interfere with fertility and pregnancy may be uncommon in these cases, but some patients can conceive spontaneous. Also in pregnancy, due to the physiologic changes of the pituitary gland, gradual volume increase and cellular hyperplasia that target hormonal secretion, the evaluation of the pituitary function is very complex.Clinical cases: We present 5 cases of female patients (24 – 35 years old) that were diagn...

Introduction: Pituitary neuroendocrine tumors (PitNET) are characterized by a heterogenous behavior. The immunohistochemical (IHC) staining of anterior pituitary hormones, along with that of pituitary transcription factors and with the clinical and biochemical characteristics of the patients can be integrated in a risk stratification system, which helps the therapeutic management.Material and Methods: We analyzed 37 patients with confirmed diagnosis of a...

Introduction: Clinically non-functioning pituitary neuroendocrine tumours (NFPitNETs) include all anterior pituitary tumours that are not hormonally active. In histopathology (HP) and immunohistochemistry (IHC), most of NFPitNETs are gonadotroph (1). Immunolabeling is negative in only 10% of cases (‘null-cell’). Occasionally, NFPitNETs are positive for GH, PRL, TSH or ACTH despite absent or only minimal secretion of these hormones in vivo, which are known as...

Background: Dopamine agonists (DAs) were associated with valvular dysfunction in patients with Parkinson’s disease due to their fibrotic effect through the serotoninergic receptor. It is more difficult to prove the same effects in patients with prolactinoma due to the lower doses, variable doses and the longer follow-up period. Aim: To assess echocardiographic features in patients with prolactinoma under DA treatment.Methods: ...
